Investigation of the special features of the coupling coefficients for microstrip asymmetric hairpin resonators at frequencies of the second passband

Compact Microwave Power Limiter with HTSC Element

“…This shortcoming is absent in HTSC power limiters designed on the basis of the new concept [5,6], where limitation occurs due to reflection, not absorption. Such device has a structure of a three-resonator bandpass microstrip filter.…”
